I read the Procede guide, and it mentions connecting the procede to the user software. However, I do not see the guide mentioning how to use the actual user software. Is there a guide that I can look at, or a location where updates are downloaded? I realize that this question might sound very ignorant, and there is probably a simple explanation that was not covered in the guide, as it was assumed to be too obvious.

I have several copies of this already, and it's precisely this that confuses me.

"The codes will be displayed on the PROcede data log screen under CAN
DME Codes."

What is the PROcede data log screen? Under how to log data, it mentions the user software. Under how to connect the PROcede, it describes that, but, again, it does not specify what the user software is, or how to obtain the user software. I'm thinking I lack a key piece of information.

the user software is the software you run on your laptop to connect to procede. when procede is connected you see a screen with round dials for rpm , boost etc. on the right you see a column with the channels set for datalogging. there you can see the codes popping up sequencially or just stay 0 if no codes.

I've researched 335i tunes long before I even got a 335i, weighing the different options, looking into how they're installed, and reading multiple user guides, including several different versions of this one. I had made the assumption that the guide would specify where to acquire the user software, but the guide does not have that piece of information, yet. It would be really cool if they included it, however. Don't call that "not even some research." I hope that answers your question.
